Chill out dude, if her car passes it passes, her car is inspected in TX not ontario so what does that matter? The companies market their products based on their peak HP/TQ gain yes, but also there are many companies out there, so you the consumer can research and make a inteligent decision. I am sorry your car has seemed to lose low end TQ, that usually isnt the case, backpressure i.e. restriction in the exhaust will almost always decrese power, One thing you need to look at is area under the curve not just how the curve is shaped, you could figure out the area under the curve mathmatically and that is a better indication of what power you picked up, i garentee that when comparing area under the curve you make more power, you may have to adapt your driving style, but you will make more power.

sorry to the originator of this post, it shouldnt have gotten this off topic.
